I'm new to plplot. I noticed that the background color is not being changed
when the device is set to 'mem'. So far as I can tell, this is because pl_bop
isn't doing anything; look at plD_bop_mem in drivers/mem.c . So I changed
plD_bop_mem as follows:
void plD_bop_mem(PLStream *pls)
{
int i;
unsigned char *mem = (unsigned char *)pls->dev;
for (i = 0; i < pls->phyxma*pls->phyyma*3;) {
mem[i++] = pls->cmap0[0].r;
mem[i++] = pls->cmap0[0].g;
mem[i++] = pls->cmap0[0].b;
}
}
and it works properly now (note that plsmem stores the -x and -y dimensions of
the memory in phyxma and phyyma).
